Hello

My problem is that my computer has been making a buzzing noise. It usually happens just at start up, but it also happens sometimes after using it for a while. I also think that the computer may be getting too hot. I never paid attention to the heat before, but it the temperature seems really high near the back and there's also a burning scent being given off. This has happened to me before on my older computer and it is usually due to a failing power supply. However I rarely had this problem with my current PC until around three weeks ago. I though that it was because the air conditioning was on a lot more than usual since we spend a lot more time at home during the summer. I think that this may have caused me problems with my system as I posted on these forums before (http://www.bleepingcomputer.com/forums/t/329963/xp-running-slow/?p=1832766). I just got a new hard drive installed yesterday so I don't think that ios the problem. What I want to know is if I should get my computer checked or can the buzzing noise be ignored. Is the sound normal running of the computers fan or could it mean that my power supply is failing?

Thanks

Hello and welcome to Bleepingcomputer.

Can you please discribe where exactly the buzzing sound is coming from?

Is it coming from the speakers?

Is it coming from the power supply?

You stated you smell something burning, it could be the power supply is over heating. Can you please post in this thread the output ratings of the power supply?

If you can post a picture of the inside of your computer and post the pic or link to it that would be helpful as well.

Kind regards.

Bruce.

Hmm...sorry I'm still not very familiar with the technical aspects of the computer, especially when it comes to hardware (and am afraid to open up the PC). Can you tell me how to post the output ratings.

I might post a recording of the buzzing sound if it will be useful, but I'm almost certain it's not from the speakers.

Also another problem I noticed is a sort of high pitched sound, which I'm not exactly sure is a beep from the speakers or a clicking/scratching noise from the fan or disc. This happened twice. The first time was followed by the Blue Screen and the second time it happened, the computer became unresponsive.

Okay I think its time you called upon someone who would be willing to open the computer's cover and have a look inside.

Your at the least getting indications that maintenance is needed.

If you can get someone who is willing to open the computer and have you post back to us, we'll post directions on what to look for and how to resolve or correct the problem.

I believe once the case is opened there may be evidence of dust accumulation somewhere in the area of cooling fans and heat sinks.

The cooling fans help move heat away from parts found inside computers, even in a very clean environment, dust traveling through the air is sucked into computers where it gets trapped.
Eventually this dust builds up to the point where it stops the cool air from getting where it needs to go, or it traps the heat from escaping.

I believe at this point, your computer needs a bit of house cleaning.

If you can not find someone to help you, you may want to take your computer to a qualified computer repair center for diagnosis and cleaning.

Bruce.

Okay thanks. Luckily there is a repair shop in the building I stay. I thought that they would have fixed everything when they changed the hard disk. Looks like they didn't. I called them to check it again. Hopefully they'll be able to get it fixed. I don't want to have to change my hard disk after just two days of use.

Using various temperature checking tools, I found out that the hard disk isn't heating up too much, but something called AUX is. It also looks like I only have one running fan in the system.

Everything seems to be fine right now. Though I do have the air conditioner on. I'll see how long it lasts.

Okay, I just had it checked and it looked like one of the capacitors got loose and the fan wasn't running properly. I got the power supply replaced. Hopefully, it'll be fine now.

It sounds to me that you're up and running again.

That is good news!

You did the best thing by bringing it to the repair shop, there was really nothing we could help you with over the net...wish there was..maybe someday that will be possible...who knows, I've discovered many things thought impossible are in fact possible.

Isn't Science wonderful? :thumbsup:

Good luck and happy computing! :flowers:
